viatom Checkme O2 Max Smart Wrist Pulse Oximeter User Manual

Introduction

Intended Use

This product is intended to be used for measuring, displaying and storing of pulse oxygen saturation (SpO2), pulse rate and motion in home or healthcare facilities environment. App can show real-time SpO2, pulse rate; get record, display results and report.

Note:

The data and results provided by this device are for pre-check screening purpose only and cannot be directly used for diagnostic or treatment. The data provided by the APP and PC software (optional) is not intended for diagnosis or treatment purpose, always consult your doctor for any health condition.

Warnings and Cautionary Advices

DO NOT squeeze the sensor or apply excessive force on the sensor & cable.
Do not use this device during MRI examination.
Never submerge the device in water or other liquids.
Do not clean the device with acetone or other volatile solutions.
Do not place this device in pressure vessels or gas sterilization device.
Consult your doctor immediately if you experience symptoms that could indicate acute disease.
Do not self-diagnose or self medicate on the basis of this device without consulting your doctor. In particular, do not start taking any new medication or change the type and/or dosage of any existing medication without prior approval.
Use only cables, sensors and other accessories specified in this manual.
Prolonged continuous SpO2 monitoring may increase the risk of undesirable changes in skin characteristics, such as irritation, reddening, blistering or burns.
Check the SpO2 sensor application site every 6-8 hours to determine the positioning of the sensor and the circulation and skin sensitivity of the patient. Patient sensitivity varies depending on medical status or skin condition. For patients with poor peripheral blood circulation or sensitive skin, inspect the sensor site more frequently.
Functional tester cannot be used to assess the accuracy of a SpO2 sensor or a device.
This device is designed to determine the arterial oxygen saturation percentage of functional hemoglobin. Factors that may degrade pulse oximeter performance or affect the accuracy of the measurement include the following: – excess ambient light – excessive motion
- electrosurgical interference
- blood flow restrictors
  (arterial catheters, blood pressure cuffs, infusion lines, etc.)
- moisture in the sensor
- improperly applied sensor
- incorrect sensor type
- poor pulse quality
- venous pulsations
- anemia or low hemoglobin -concentrations
- cardiogreen and other -intravascular dyes
- carboxyhemoglobin
- methemoglobin
- dysfunctional hemoglobin

TAKE THE FIRST RECORDING START.

Wear the device and the Ring Sensor, press the button to power on. And keep yourself in the quiet environment. (For the sake of clarity, recommended the user wear the monitor watch on their left wrist and put the ring sensor on the thumb. If it is too tight, try another finger. Avoid being loose.)

TAKE THE FIRST RECORDING START

STOP. After the record, take off the Ring Sensor (and the device), the recording will be save after the countdown. (If the working time is less than 1 minute, the data will not be saved.)
Using Instructions

Note:

Please avoid excessive motion for the sensed finger during recording and avoid any strong ambient light condition.

Stop monitoring & sync data

Take off the sensor, the countdown will begin.
During the countdown, if you wear the sensor again, the record will be resumed.
After the countdown, the data will be ready for sync.

Note: The duration of the recording is 1mins~10 hours. And the device can collect and store maximum 4 recording, when the 5th recording coming, the first recording will be will covered.

Sync data to the ViHealth App
You can Sync the data to your app after the countdown or next time after you turn on the device.
Note: Refer the ViHealth app manual for more details.

Measurement accuracy verification: The SpO2 accuracy has been verified in human experiments by comparing with arterial blood sample reference measured with a CO-oximeter. The pulse rate accuracy has been verified by Emulator. Pulse oximeter measurement are statistically distributed and about two-thirds of the measurements are expected to come within the specified accuracy range compared to CO-oximeter measurements.
